19 Claims. (Cl. 6920) This invention relates to portable devices for processing fur or fur. garments or piled sheets.

An object of this invention is to provide a highly improved machine of the character described having means for combining brushing, ironing, and cleaning fur or like material having a pile or hair, and for producing a sheen and generally improving the appearance of fur or fur garments.

Another object of this invention is to provide a device or machine of the character described which shall have the following features or parts:

1. A nose which carries roller and heating unit, is removable in order to facilitate change of roller, change of heating unit, and making adjustment or change in gears which drive the roller.

2. Fire walls: One between a motor chamber and a pulley compartment and one between the pulley compartment and the blower housing (air rotor housing). The fire walls keep heat of roller (4.00 F.) out of pulley housing and away from motor.

3. The air rotor housing is placed and designed so as to suck and control the air from the bottom opening of the machine, and yet not cause any air turbulence which would produce back pressure. Air rotor housing is mounted on the forward fire wall.

4. A base removable for accessibility and repair of workable parts of machine.

5. A handle arranged so as to be forward of center of gravity in order to balance the motor which is at the back of the machine and is heavier than the nose of the machine, so that as the ma chine is used, the tendency is to push the nose forward and down and so keep the base in a horizontal plane. When at rest the machine tilts back so as to keep the hot roller off the table or work.

6. The wires through the handle. The handle is so designed (split hollow handle) as to receive wires without exposing same to heat. The handle is insulated so as not to heat up. Location of switch makes it readily accessible to fingers of operator when using machine.

'7. The thermostat controls the heat unit in roller through range of 90 F. to 400 F. Knob for thermostat is located in accessible place. Thermostat is in housing to one side where there is room for it.

8. Gearing: No belt for roller, that is between air rotor and roller. Right angle drive is made operative through a Worm gear arrangement through longitudinal center line of machine. A counter shaft is supported 01f left hand Wall of casing to which is connected a reduction gear which drives the roller.

9. Eye bolts for a counter balance (three eyebolts).

10. The bolts to bolt the handle to the casing. If wiring goes wrong, it is only necessary to take out two bolts which bind handle to housing studs and to pull the handle up for wiring adjust-- ment or repairs. If further wiring repair to handle is necessary removal of the upper two screws which hold both halves of handle together will expose all wiring for necessary adjustment.

Yet another object of this invention is to provide a strong, compact and light machine of the character described which shall be relatively inexpensive to manufacture, easy to handle, and yet practical and efiicient to a high degree in use.

Other objects of this invention will in part be obvious, and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the fOllOWing claims.

The recesses 104 have countersunksemi-circular enlarged portions l5, as'shown inFig. 7. 4

Fitted at the front of th'ba'se' plate and at the lower end of front wall 61 of the cover is a nose member or roller support H0. Said roller sup port has a top straight arm III provided with surfaces contacting surfaces 69 and shoulder of the cover. Inclined downwardly and forwardly from wall I II is a wall H2 from which there extends a downwardly and inwardly curved arm H3. The rear edge H3a of arm H3 is parallel to and spaced from the forward edge H4 of the bottom wall 93 of the base plate, thereby forming an opening I I5 in the bottom of the machine. At the ends of member H0 are end walls H6 having back edges H1 contacting surfaces 10 and 95 of the cover 60, and base plate 92, respectively. Said side walls H6 are formed adjacent the rear edges with semi-circular recesses I I8 complementary to the recesses I04 and forming therewith circular openings. At the inner sides of the walls H6 and 94 are formed annular recesses I I9 to receive ball bearing races I20. The nose member or roller housing H0 is attached to wall 61 by means of screws I2I passing through walls III and 61 and to front edges 95 of side walls 04 by screws I23.

On the curved wall 68 of the cover 60 is an eyelet I similar to the eyelets 26. It will now be observed that the machine can be hung on a counterbalance by engaging the eyelets 26 and I25.

The wall 6I adjacent the notch 15 is formed with a horizontal through opening I30. The outer end of the opening is screw threaded to receive a set screw I3I. Within said opening is a ball bearing I32. Attached to the inner surface 14 of front wall 61 is an angular bearing bracket I33 having an arm I34 contacting said inner surface and an arm I35 extending at right angles thereto and parallel to the wall 6I, which has the opening I30. It will be noted that the shaft 82 is located between arm I35 and the last mentioned wall 6I. Arm I35 carries a bearing I36 aligned with the bearing I32. Rotatably mounted on said bearings is a horizontal transverse shaft I31 disposed below shaft 82. On shafts I31 is a worm wheel I38 meshing with the worm 83. Fixed to said shaft I31 and adjacent the inner surface of the wall 6| which has the opening I36 is a pinion I40.

Rotated on the ball bearings I I9 is a roller I4I. Mounted on one end of the roller is a pinion I42 meshing with the gear of pinion I40. Said roller is formed with an axial throug'h opening I44 through which there passes a heating unit I45 received Within the bearings I I9. Said roller MI is located between the side walls 94 of the base plate and between the side walls I I6 of the roller support. Said roller MI is formed with a pair of opposite flat surfaces I41. Extending from said flat surfaces I41 are part cylindrical surfaces I48. Said part cylindrical surfaces I48 terminate in helical edges I49. Extending from the edges I49 are undercuts I50, also extending helically. Extending from the bottom of the undercut surface I50 to the flat surfaces I41 are part cylindrical surfaces I5I. Attached to the roller on each of the flat surfaces I41 is a helical row of combing pins I52. The roller may be formed with drilled openings extending to the axial opening I44 thereof, and the pins I52 are force fitted into said openings and extend therefrom.

The heater I45 extends through the axial opening I44 and heats the roller. It will now be understood that when the motor is operating, the rotor fan will rotate through belt 88 and shaft 82 and the roller will rotate through pinions I42 and I40, shaft I31, worm wheel I38, worm 83 and shaft 82. The motor thus serves to rotate the roller and at the same time rotates the fan 90. The fan is so arranged as to provide a suction through the opening H5, thereby causing air to blow upwardly through sleeve 13. The fur or other material over which the machine is moved will be combed by the teeth I52, will be ironed by the surfaces I48, will be brushed by the edges I49 and will be heated by the heated roller.

Mounted on sleeve 13 is an outlet member or can I50a. Said outlet can I50a comprises a vertical tube I5 Ia fitted within sleeve 13. The lower end of tube I5Ia communicates with the interior of the air rotor housing 5| through wall 52. Attached to the upper end of tube I5Ia is a horizontal outwardly extending tube I52a. Extending from the upper end of sleeve I5Ia is an upwardly inclined baffle plate I53. At the outer end of tube I52a is an adapter I54 carrying a screen I55. The air passing outwardly through tube I52a is thus screened by the screen I55.

Dust collected within the can or outlet tube may be removed and cleaned, if desired. The adapter I54 is preferably mounted on tube I52 by means of bayonet pins I56, which pass through appropriate bayonet slots in said tube. Interconnecting the studs 23 and 64 is a handle I60. The handle may be made of Bakelite or other heat and electrically insulating material. It is split longitudinally and is hence formed of two parts I6I and I62. The parts I6I, I62 have meeting surfaces I53. Said handle parts each have a straight portion I65 and downwardly and outwardly inclined portions I66 and I61. The part I62 is formed with a slot or groove I63 extending from one end to the opposite end thereof. The slot I68 is, of coursegcovered by handle part I6I. Wall 68 of the cover 60 is formed with an opening I10 adjacent the stud 64. Opening 24 communicates with one end of groove I68, whereas opening I10 communicates with the other end of the groove I68. A conduit is thus formed interconnectin the motor housing II with the front housing or cover 68. Suitable wiring for the motor passes through the groove I68. The handle parts I6I, I62 are formed with complementary grooves I12 at their meeting faces, to form a socket to receive the stud 23. Said handle parts are also formed with complementary recesses I12 at their meeting faces to receive stud 64. Between the studs 23, 64 and the handle parts are insulating spacers or sleeves I16. Between the rear end of the handle and the motor housing is a heat insulating spacer plate I80. Between the front end of the handle and the housing 60 is a similar spacing plate I82. Within the openings 25 and 65 of the studs 23 and 64, respectively, are bushings or sleeves through which extend bolts I84 for fixing the handle to said studs. The handle parts are furthermore interconnected by transverse bolts I85. Within the handle formed by the cover 68 and attached to the inner surface of one of the inclined walls 62 and adjacent the end of the chamber where the pinion or gear I40 is located, is a thermostat I controlled by a knob IOI, disposed at the outside of the cover. The knob is provided with a shaft I02 passing through a suitable opening in the cover for operating the thermostat. Such thermostat may be of well known construction, such as Model A- manufactured by General Thermostat Company of New York.

On the handle part I62 is a toggle switch I85 .housingfifi. The screws 1 wmcnma be,insertedir anysuit bl et e thermostat I99 is,.c,onnected ;in.ser c r nit with the;heatin -lmi leeb irire i herm stat andlneatlng unit areioonnected ;i nis eries circuitto the plug 91 and are .p
